A prioritization method for random access, comprising receiving one or more first packet flow for transmission, wherein the one or more first packet flow is assigned a respective access category queue, initiating a random access procedure for the first packet flow, receiving a packet of a second packet flow for transmission, wherein the second packet flow is assigned an access category queue having priority over the access category queue assigned to the first packet flow, issuing an indication configured to interrupt the random access procedure for the first packet flow, and performing a random access procedure for the received packet of the second packet flow wherein idle time slots previously sensed by the random access procedure for the first packet flow are considered as sensed also for the random access procedure for the second packet flow. Corresponding apparatus and computer program product are also disclosed.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method according to claim 1, further comprising performing additional channel sensing if further idle time slots are needed.
3. The method according to claim 2, wherein channel sensing comprises a Listen-before-talk, LBT, procedure or a Clear Channel Assessment, CCA, procedure.
7. The method according to claim 1, further comprising resuming random access procedures for the first packet flow once the second packet flow has been processed.
8. The method according to claim 1, wherein the random access procedure comprises a contention-based random access procedure.
9. The method according to claim 1, wherein the first and second packet flows originate from a time sensitive networking, TSN, traffic flow.
10. The method according to claim 1, wherein the method is implemented in a Wireless Local Area Network, WLAN, radio network.
13. The apparatus according to claim 12, wherein the controlling circuitry is further configured to cause performance of additional channel sensing if further idle time slots are needed.
17. The apparatus according to claim 12, wherein channel sensing comprises a Listen-before talk, LBT, procedure or a Clear Channel Assessment, CCA, procedure.
18. The apparatus according to claim 12, wherein the controlling circuitry is further configured to cause resumption of random access procedures for the first packet flow once the second packet flow has been processed.
19. The apparatus according to claim 12, wherein the random access procedure comprises a contention-based random access procedure.
20. The apparatus according to claim 12, wherein the first and second packet flows originate from a time sensitive networking, TSN, traffic flow.
